Mammilian circulation

Question 1

Trace path of blood

Answer 1

Begins in right ventricle pumping blood to the lungs via the pulmonary arteries –> In the lungs, blood loads O2 and unloads CO2 –> Oxygen rich blood from the lungs enters the heart at the left atrium via pulmonary veins –> It is pumped through the aorta to the body tissues by the left ventricle –> the aorta provides blood to the heart through the coronary arteries –> blood returns to the heart through the superior vena cava (blood from head, neck, and forelimbs) and inferior vena cava (blood from trunk and hind limbs) –> the superior vena cava and inferior vena cava flow into the right atrium

Question 2

Pulmonary circuit

Answer 2

the circuit through the lungs where blood is oxygenated

Question 3

Systemic circuit

Answer 3

the circuit through the rest of the body to provide oxygenated blood
